18.3 Coulomb’s Law The magnitude of the electrostatic force exerted by one point charge on another point charge is directly proportional to the magnitude of the charges and inversely proportional to the square of the distance between them.
Let’s solve some problems from the book …
The Electric Field Point charge q: The electric field does not depend on the test charge. Point charge q:
